* AlternateCharacterInterpretation: The third brother was just as screwed as the others. Demanding invincibility and the power to raise the dead are both pretty hubristic, but so is the demand to hide from Death. Brother Number Three spent his entire life hiding away from the world, unable to meaningfully interact with other people, unable to truly live. And what happened to him in the end? He welcomed Death as a friend, committing suicide just like the second brother, because his hollow life had become unbearable. The Cloak is just as much a curse as the other Hallows.
* FreudWasRight: Dumbledore notes that all the claimant owners of the super-powerful Elder Wand have been men, adding "make of that what you will."
* ValuesDissonance: In the context of Potterverse; Babbitty Rabbitty feels no compunction about threatening to use a curse later declared Unforgiveable and outlawed.
